Zusammenfassung:	The present disclosure relates to a method of designing a spherical microstructure mold (604-614) module to be incorporated into a calendering roller (600) for generating a microstructure (108) on a planar surface (104), comprising calculating a first curvature (204) on a cross-sectional planar surface (202) for a first microstructure point of the spherical microstructure mold module, calculating a second curvature (210) of a spherical surface (102) of the spherical microstructure mold module, measuring a radius (214) of the spherical surface (102), the radius (214) being from the center of the spherical surface (102) to the first microstructure point, and determining a location of the microstructure (108) on the planar surface (104), the location being derived from the first curvature (204), the second curvature (210), and the radius (214).
